Summary heading
This series consists of diapositives of aerial photography
for mapping projects undertaken by the Division of National Mapping (Natmap),
Australian Survey Office (ASO) and Australian Surveying and Land Information
Group (AUSLIG).
Function and purpose
Diapositives for mapping projects undertaken by the Division
of National Mapping (Natmap), Australian Survey Office (ASO) and Australian
Surveying and Land Information Group (AUSLIG) are organised
by 1:250 000 map area for projects undertaken by Natmap, and by film number for
ASO and AUSLIG projects.
Diapositives were only produced when mapping projects were
undertaken. For example photography may have been flown, but the diapositives
may not have been produced until the next financial year when more money was
allocated. If less money was available then diapositives may not have been
produced at all. Therefore not all films have an associated set of
diapositives.
All projects were for specific areas, though the intent of
the Natmap projects was to eventually have a national coverage of photography.
These areas could range from general mapping projects, for example up to 5 x
1:250 000 map sheet areas, also known as a “block” or “block photography” to
very specific areas, such military and civil areas referred to in CRS A892, CRS
A895 and CRS K1301 generally referred to as “project” photography.
The last diapositives used by the Commonwealth for civil
mapping projects were produced in 1989.

Language of material
Physical characteristics
The diapositives are a positive photographic image on
transparent material for example a photographic slide or lantern slide. All the
items in this series are on polyester based film cut to the format size of the
file (23 x 23cm). The images are mostly black and white however there is a
possibility of some images to be in colour.
System of arrangement and control
The diapositives are arranged by the film number which is
single number with “SO” or “SOC” prefix. “SO” denotes that the image is black
and white and “SOC” signifies that the image is in colour.
